Propagation Modeling at 60 GHz for Indoor Wireless LAN Applications

This paper reports narrowband and wideband results derived by propagation modeling at 60 GHz for indoor WLAN applications. A multi-ray model is proposed and verified through a simulation process. The propagation in the site-specific environment can be described using 4-5 rays without reducing the accuracy of the results. RMS delay spread varies with distance from 0.57 ns up to 2.32 ns. Coherenc...

Dynamic Double Directional Propagation Channel Measurements at 28 GHz

This paper presents results from the (to our knowledge) first dynamic double-directionally resolved measurement campaign at mm-wave frequencies for an outdoor microcellular scenario. The measurements are performed with USC’s realtime channel sounder equipped with phased array antennas that can steer beams electrically in microseconds, allowing directional measurements in dynamic environments. E...

Multipath Propagation Measurements in Radio Links at 40 Ghz

The results of a measurement campaign conducted to determine the wideband behaviour of the radio channel assigned to Multimedia Wireless Systems are described in this paper. It has been found that small multipath components are present in the impulsive response of radio channels operating at 40 GHz with 80 MHz bandwidths. Multipath and delay spread are limited by the spatial filtering of direct...
